LPC1769 as RS485 slave device

Question asked by kalpeshbalar on Mar 26, 2017

Hi, I am trying to use LPC1769 as RS485 slave device. And LPC11C14 used as master device.

Attached are master and slave program files.

 

If I enabble RECEIVER_ALWAYS_EN = 1 in slave then I am able to recive data on slave from the master.

But when I enable AUTO_SLVADDR_DETECT=1 in slave, I am not geting any data from master to slave.

What clould be wrong in attached master slave programs?

 

Thanks,

KBalar
